3 Claims. (Cl. 299-143) Lubrication in modern high speedl machines must be supplied in the correct quantity and in the correct places. This is particularly true of machines incorporating antifriction bearings on relatively high speed shafts where over lubrication will cause overheating and insufficient lubrication will cause destruction. A, To this end, applicant uses'v lubricant in the form" of mist which settles on moving parts and properly lubricates all members in the usual power train.

Means of forming mist are generally old but in proper mist lubrication economy and simplicity are important factors, as well as the need ltoprovide mist particles of Athe proper size and quantity. Intersecting streams of oil issuing from jets will cause mist but it is difficult to cause the stream paths to intersect unless the volume of oil flowing is very large, and thus inefficient. Another case is of a jet issuing against a surface, which also causes mist. Inv this case the mist lparticles are large and the amount of the flow reduced to mist is not great enough to consider this device'eflicient. Much of the oil issuing fromthe jet is not atomized but runs away in a solid stream. Higher pressures obviate some of these difficulties, but again render the device inefficient.

It is thus an vobject of this invention to provide a device that efliciently produces mist from oil under pressure in a manner that provides mist particles of the` proper size.

' United States Patent O Nagle V..Guscbing, Sidney, Ohio, assgnor to-The Monthat the oil will pass across theface of lthe jets. That-is to say, the oil running down the face 32 will pass into occur at face 26'and the jet issuing-from orifice 28.

The jets 22 and 28"issue at an angle to, rather than parallel to, faces 32 and 26 respectively.

It should be noted that complete atomization does not occur but some oil continues to pass along paths 24 and to continue supplying oil to run down into the paths of the jets issuing from orifices 22 and 28. It should be particularly noted from Figure l that the jets do not intersect each other in the air but are offset relative to each other.

Referring now to Figure 3, another embodiment of the invention is seen. A body 34 is provided with arms 36 and 38. Arm 38 is providedwith an oil supply passageway'or conduit 40 through which oil under pressure is supplied and this passageway terminates in an orifice 42 which directs a jet of oilalong path 44, which is away from arm 38 in which orifice 42 is mounted to impinge upon the inner face 48 of arm 36. As is well known from cases where impngement of this type occurs, the oil splashes around and atomizesto a small extent. Some of the splashing oil contacts the under face 50 of the body 34v and runs down the slope thereof until it drips It is another objectof this invention to provide a simembodiment of my ingenerally along the line Il-II of Figure 1,

Figure 3 is a side elevation of another embodiment of my invention, and

Figure 4 is a side elevation of a further embodiment of my invention.

Referring now to Figures l and 2, the mist lubricator comprises arbody 10 h avingagenerally straight base member 12'` with two upstanding arms 14 and -16 located thereon at opposite ends thereof. Passageways or conduits 18, 19, and 20 are provided in the body 10 with passageway 18 connected to both passageways 19 and 20. Passageway 19 terminates van orifice 22 and when oil under pressure is supplied to passageway 18 it issues from the orifice 22 as a jet which-moves freely in the air and follows path 24 to strike upon the inner face 26 of arm 14. A certain amount of the oil issuing from orifice 22 atomizes upon striking lface 26 but a significant portion of the oil runs down the face 2 6.

Passageway 20 is terminated by an orifice 28 from which issues a jet of oil generally lfollowing path 30 through the air to strike face 32 on the inside of arm 16. Here again the oil runs down the face 32 and it will be seen over the jet issuing from orifice 42. Again when this occurs, the jet andthe flow of oil from face 50 into the path l44 of the jet atomize causing mist particles of the proper size. Sufficient oil is unatomized and passes along path 44 to keep oil running down face 50 to pass into the path of the jet.

Referring now to the embodiment of Figure 4, a body 52v is shown as having a passageway or conduit 54 which is supplied with oil under pressure. Passageway 54 terminates in an orifice 56 and side passageway 58, connected lwith passageway 54, terminates in an orifice 60. Lo-

cated over the orifice 60 is a cover plate 62 which is held to the body 52 by fastening means such as screw 64. When passageway 54 is supplied with oil under pressure some of the oil issues from orifice 60 and some of it issues from orifice 56 creating a jet directed away from body 52. The oil issuing from orifice 60 is deflected from the under side of cover plate 62 and then runs down the top face 66 of the body 52 and thence runs into the path of the oil issuing from orifice 56. As was earlier described, droplets passing into the path of such a iet cause atomization of both the droplets and the jet into mist particles of the proper size for proper lubrication.

The embodiments shown and described are also effective with liquids other than oil.

While I have illustrated my invention in the above described preferred embodiments it can easily be seen that this invention is capable of further embodiments. 'Iherefore I request that the scope of this invention be defined by the appended claims.

What I claim is:

1. In a device for producing mist, first and second surfaces arranged so that they substantially face each other, first and second orifices in said first and second surfaces, respectively, a conduit of substantially larger sizethan saidv orifices connected to both said orifices and arranged to beconnected to a supply of liquid under pressure, said first and second orifices thus emitting jets of liquid when said conduit is supplied with liquid under pressure, said first orifice being directed so that its fluid jetimpinges upon said second surface above said second orifice,

. said first surface above said i 2,155,135 atented July 17, .1956.:

from said rst and second orifices runs down said second and first surfaces to partially interrupt the jets issuing from said second and first orifices, respectively, to cause mist.

2. The structure of claim l wherein the liquid supply is lubricating liquid under pressure so that a mist of lubricating liquid is created.

3. In a device for producing mist, a plurality of surfaces, a plurality of orifices, said orifices being arranged to be connected to a common source of liquid under pressure, at least one of said orifices being in each of said plurality of surfaces andeach of said orifices being directed toward another surface at a point on said another surface above the orifice in said another surface, said orifices being directed so that iets issuing therefrom when said orifices are supplied with liquid under pressure 4 are uninterrupted by impingement with other jeta, whereby liquid running down the surfaces partially interrupts the jets to cause the creation of mist.
